• Scheduled Action
  1. Upon installing the module, a daily scheduled action "Run attachments compression rules" is added automatically

How it works

• Add pdf: Add some pdf attachments that contains images in the models.
  In the following example, we selected the sale model in my compression rule. So, we are adding 2 pdf files which contain images.

• Run the compression rule: Go to the corresponding compression rule and run it. The pdfs satisfying these rules should be compressed.
  The system will show a pop up with the details of the compression:
  compressed pdf and total size reduction

• Check results: Go back to the model where the pdf was uploaded and verify the results.
  Download the pdf and check the size reduction.

• File Store: Notice that upon running a compression rule or when the scheduled action runs them,
  the size of the filestore is reduced if Replace All was checked
